STELZNER® agricultural measurement systems

For measuring activity, pH and conductivity

The Type-X combination kit consists of three instruments: the PET 2000 for measuring soil activity (in g salt/l); the pH AGRAR 2000 for measuring soil or liquid pH values; and the EC 2000 for measuring the conductivity in liquids.

The PET 2000 allows you to determine the activity or total salt content (in grams of salt per litre) in the soil or substratum. The activity is determined by the amount of dissolved salts contained in the soil. The mobility of the salts is dependent on the humidity, temperature and density of the soil. This allows nutrient salts that are available to plants (such as nitrate or potassium) to be fully measured. This provides you with a concise overview of what nutrient salts are available to plants in the root zone.

The pH AGRAR 2000 is also included for monitoring the pH value. This microprocessor-controlled meter enables you to make quick and precise measurements in solutions such as irrigation water and fertilizer solutions. A glass pH piercing electrode allows you to determine the pH level directly in the soil or substratum. The meter comes with automatic calibration. It displays the electrode conductivity slope for monitoring the glass pH piercing electrode. A warning tone is emitted if the sensitivity level is too low. The sturdy housing is built for the rough conditions of agricultural field work.

The EC 2000 conductivity meter completes this instrument kit. EC value analysis is a critical component in fertilization, soil-free cultivation, closed cultivation, hydroponics, or salt-sensitive crops. With its ability to measure up to 200 mS/cm, the EC 2000 is also suitable for monitoring basis solutions. It is temperature compensated and equipped with a specific conductivity electrode with integrated temperature probe.
